How to use the auto/truck key blank

SYSTEMS
Immobilizer System: System used in disarming vehicles when an improper or non-transponder key is used.
The first component disarmed in most systems is the Fuel Pump.
PATS: Passive Anti-Theft System (Ford).
Securilock: Name for Ford PATS System.
PASS Key® III: Personalized Automotive Security System (Registered Trademark - GM).
PASS Key® III+: Current generation (2004-05) of the PASS Key ® III.
Passive: Requires that the user do nothing to Arm or Disarm. The system is automatic.
Fixed Code: The code required to start the vehicle does not change.
Rolling Code: This system is more complex. Each time the ignition is turned on, the engine has started and the
transponder code is checked by the vehicle computer memory, a new code is written to the transponder. This
new code is required for the car to start the next time.
Challenge Response Code (Encrypted): This system is the most complex of those currently in use.
Communication between the key and the ECM is encrypted in both directions (bi-directional encryption of data)
and the code changes during every use. In most cases, Ilco offers a solution to this system.
SYSTEM COMPONENTS
Transponder: Radio Frequency (RF) Transmitter Responder reacting to an electrical impulse of a reader constituted
by a surrounding antenna.
Electronic Control Module (ECM): The ECM, or on-board computer, in a vehicle with an immobilizer system
has special software designed to work with the immobilizer. The immobilizer can communicate only with an
ECM, which it recognizes.
Control Module: The control module communicates with the transponder in the ignition key via the antenna ring,
as well as with the ECM. The control module sends a carrier frequency via the antenna ring. The frequency can
be changed to the best possible frequency if needed. A fixed number of codes are contained in the memory and
the Control module verifies that the correct code is being sent.
Antenna: The antenna has two functions. It transmits the carrier frequency from the control module to the transponder
and transmits a coded identification signal from the transponder to the control module.
TRANSPONDER CHIPS
Read-Only/Fixed Code: This type of chip is used on most original transponder keys. The code can be read,
but it cannot be written over.
Read-Write/Fixed Code: This type of chip is used on Ilco after market keys. The transponder code can be read
and programmed over.
PT: This key suffix refers to Ilco replacement keys containing pre-programmed chips.
T1: This key suffix refers to a first generation pre-programmed Philips read/write chip used mainly in Europe.
T2: This key suffix refers to a second generation pre-programmed Philips read/write chip and is used on some
Ilco replacement keys.
T3: This key suffix refers to a glass Texas Instruments pre-programmed read only chip.
T4: This key suffix refers to a plastic wedge Texas Instruments pre-programmed read only chip.
T5: This key suffix refers to a blank or neutral transponder contained in the key head. This is a read-write chip
used in most Ilco replacement keys that are used in conjunction with the RW2 or RW2, RW3, RW4/Ilco EZ ® -Clone.
T6: This key suffix refers to a blank with a Megamos encrypted read only chip.
T14: This key suffix refers to a plastic wedge Philips CAN encrypted (ID46) pre-programmed read only chip.
T24: This key suffix refers to a glass Megamos CAN encrypted pre-programmed read only chip.
Texas Instruments (TI): This chip manufacturer produces both plastic wedge and glass transponder chips.
Chips are read-only. Texas Instruments chips for Chrysler and Lincoln LS are encrypted (Challenge Response).
